This would be interesting, turn some brews around within a week or two finished product. Let me know if you try this and how it goes.I would echo the same. I use the pro.... with C kegs. When cold crashed, I rack it to corny kegs. the adapters make it easy to use either.
On a different topic, anyone ever used a traditional Norwegian kveik yeast in a pico pak? The fermentation range up to 98 degrees combined with the valve for fast ferment, seems attractive. I wonder if 3-5 days fermentation is actually reality. I was looking at the Gjernes farmstead, Voss Kveik’s profile looked pretty darn good.
Anyhow, if anyone used those in the past, I'd love to hear more.
